Problems solved by technology

[0003] When the submarine cable is arranged in the ocean, in order to facilitate the transportation and installation of the submarine cable, its length is limited, so the submarine cable will have joints during installation. Due to long-term immersion in seawater, the joints will be damaged during long-term use. Corrosion, aging and loosening occur, which will affect the overall transmission work of the submarine cable

Embodiment 1

[0026] refer to Figure 1-4 , a device for preventing scouring of buried deep sea cables, comprising a protective cylinder 1, a scouring roller 2 is arranged on the outside of the protective cylinder 1, and the inner wall of the scouring roller 2 is connected with a plurality of paddles 3 by bolts, and the multiple paddles 3 are ring-shaped The outer wall of the protective tube 1 is provided with two annular grooves, and the inner wall of the annular groove is connected with a sound board 4 through bolts, and the outer wall of the sound board 4 is connected with a plurality of sounding pieces 5 through bolts, and the plurality of sounding pieces 5 are connected to each other by bolts. The surface of the sound board 4 is inclined, and the inside of the protective tube 1 is provided with a plurality of circular pipes, and the outer wall of the protective tube 1 is provided with a loudspeaker port 6, and the inside of the loudspeaker port 6 is provided with a water barrier, and th...

Embodiment 2

[0035] refer to Figure 5 , a device for preventing the erosion of buried deep sea cables. Compared with Embodiment 1, this embodiment also includes a square groove on the upper side outer wall of the base 16, and a backing plate 21 connected to the inner wall of the square groove by bolts, and the backing plate 21 The outer wall of the upper side is provided with a plurality of anti-collision protrusions 22, and the material of the anti-collision protrusions 22 is rubber

[0036]When in use, the inserting rod 19 is inserted into the soil at the bottom of the ocean, and the device is fixed in the ocean as a whole. After installation, the flow of water inside the ocean is blocked by the resistance plate 7, and the kinetic energy in the flow of the water body is converted into the energy of the resistance plate 7. Thrust force, the washing roller 2 rotates outside the protective cylinder 1. During the rotation of the washing roller 2, a plurality of plectrums 3 are constantly in...

Abstract

The invention belongs to the technical field of submarine cable engineering, particularly relates to a device for preventing a deep-buried submarine cable from being scoured, and aims at the phenomena that a connector is corroded, aged and loosened due to the fact that the connector is soaked in seawater for a long time and the connector is used for a long time when the submarine cable is installed. A protective cylinder is included, a scouring roller is arranged outside the protective cylinder, a plurality of shifting pieces are fixedly connected to the inner wall of the scouring roller and distributed annularly, two annular grooves are formed in the outer wall of the protective cylinder, soundboards are fixedly connected to the inner walls of the annular grooves, and a plurality of sounding pieces are fixedly connected to the outer walls of the soundboards. Water flow in the ocean is utilized to drive the scouring roller to rotate, the situation that a submarine cable connector is corroded under frequent seawater scouring, and consequently the connector is loosened is avoided, meanwhile, water flow in the ocean is utilized to drive the shifting pieces and the sounding pieces to make contact to produce sound, and the purposes of expelling fish schools and protecting submarine cables are achieved.

Description

technical field [0001] The invention relates to the technical field of submarine cable engineering, in particular to a device for preventing erosion of buried deep submarine cables. Background technique [0002] Submarine cables are cables wrapped with insulating materials and laid on the seabed for telecommunication transmission. Submarine cables are divided into submarine communication cables and submarine power cables. Modern submarine cables use optical fibers as materials to transmit telephone and Internet signals. Submarine cables have It has the advantages of less investment, fast construction speed, safety and stability, strong anti-interference ability and good confidentiality performance. [0003] When the submarine cable is arranged in the ocean, in order to facilitate the transportation and installation of the submarine cable, its length is limited, so the submarine cable will have joints during installation. Due to long-term immersion in seawater, the joints wil...
